An interventional study of AI-assisted Bowel Preparation Management and Conventional Bowel Preparation Management in Colorectal Polyp, Colorectal Adenoma and Bowel Preparation, sponsored by Shandong University. Not yet recruiting at 1 site in China. Open to participants aged 18 Years to 75 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-28.

Colorectal cancer (CRC) is one of the most common malignancies worldwide, and colonoscopy is an important method for CRC screening and early detection. The effectiveness of colonoscopy is closely related to the quality of bowel preparation. However, inadequate patient understanding and poor adherence to bowel preparation instructions may reduce preparation quality.
This randomized controlled trial aims to evaluate the effectiveness of an artificial intelligence (AI)-assisted bowel preparation management system based on WeChat in patients undergoing colonoscopy. Participants will be randomly assigned to either an intervention group receiving AI-assisted bowel preparation guidance and management through WeChat or a control group receiving conventional bowel preparation education and management.
The study will compare bowel preparation quality between the two groups and assess whether AI-assisted management can improve patients' adherence to bowel preparation instructions and the overall effectiveness of bowel preparation.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants assigned to the intervention group will receive AI-assisted bowel preparation guidance and management through WeChat in addition to standard bowel preparation.
Behavioral: AI-assisted Bowel Preparation Management
Participants in this group will receive conventional bowel preparation education and management according to routine clinical practice before colonoscopy.
Behavioral: Conventional Bowel Preparation Management
Participants assigned to the intervention group will receive AI-assisted bowel preparation guidance and management through WeChat in addition to standard bowel preparation. The system provides guidance and support throughout the bowel preparation process before colonoscopy.
Participants assigned to the control group will receive conventional bowel preparation education and management according to routine clinical practice before colonoscopy.
Bowel Preparation Quality Assessed by the Boston Bowel Preparation Scale (BBPS)
Bowel preparation quality will be assessed using the Boston Bowel Preparation Scale (BBPS). The total BBPS score ranges from 0 to 9. Excellent bowel preparation is defined as a total BBPS score ≥8. Adequate bowel preparation is defined as a total BBPS score ≥6, with a score ≥2 in each colonic segment.
Time frame: During colonoscopy.
Polyp Detection Rate (PDR)
Polyp detection rate is defined as the proportion of participants in whom at least one colorectal polyp is detected during colonoscopy.
Time frame: During colonoscopy.
Adenoma Detection Rate (ADR)
Adenoma detection rate is defined as the proportion of participants in whom at least one histologically confirmed colorectal adenoma is detected during colonoscopy.
Time frame: From colonoscopy to completion of histopathological assessment.
Cecal Intubation Rate
Cecal intubation rate is defined as the proportion of colonoscopy procedures in which the colonoscope successfully reaches the cecum.
Time frame: During colonoscopy.
Insertion Time
Insertion time is defined as the time from insertion of the colonoscope through the anus to successful intubation of the cecum.
Time frame: During colonoscopy.
Withdrawal Time
Withdrawal time is defined as the time from the start of colonoscope withdrawal from the cecum to complete removal of the colonoscope.
Time frame: During colonoscopy.
Patient Satisfaction
Patient satisfaction with bowel preparation education and management will be assessed after completion of bowel preparation using the study-specific satisfaction questionnaire or rating scale.
Time frame: Day 1 (After completion of bowel preparation and before colonoscopy)
Patient Tolerance
Patient tolerance of bowel preparation will be assessed based on sleep quality during bowel preparation and willingness to undergo the same bowel preparation regimen again in the future.
Time frame: Day 1 (After completion of bowel preparation and before colonoscopy)
Bowel Preparation-related Discomfort Symptoms checklist
Bowel preparation-related discomfort symptoms, including abdominal pain, abdominal distension, nausea, vomiting, and other adverse symptoms, will be recorded after completion of bowel preparation.
Time frame: Day 1 (From the start of bowel preparation to colonoscopy)
